Abstract
The present invention relates to a kind of methods preventing storage spontaneous combustionof coal, coal are placed in closed space and oxygen-barrier, can also coal be carried out premature oxidation processing so that coal loses the condition of spontaneous combustion.The present invention, using the design being kept in dark place, prevents coal from causing coal fever to cause spontaneous combustionof coal in turn due to receiving illumination by setting coal saving space to vacuum state；Another method is to decompose the property for generating oxygen under certain condition by using oxidant so that coal is under the encirclement of oxygen, extends the time of its spontaneous combustion, can be widely popularized in energy development field.
Description
Technical field
The present invention relates to chemical reagent technical field, in particular to a kind of methods preventing storage spontaneous combustionof coal.
Background technology
Currently, in order to save space, coal placement generally in heaps in storage, this allows for the coal for placing the long period
Charcoal is easy fever, when the heat that coal generates is more than the heat distributed around, and in the case of air circulation, then can draw
Spontaneous combustionof coal is played, for just mined coal, the active group on surface is easy to be oxidized by oxygen, and is storing
It is easier to lead to surface oxidation in the process and then causes spontaneous combustionof coal.There are two the conditions for causing spontaneous combustionof coal, when coal with
Oxygen contacts, second is that heating value of coal.Therefore, it if to effectively prevent spontaneous combustionof coal, needs coal and oxygen-barrier, or
Person reduces heating value of coal.
Invention content
In order to solve the above technical problems, technical solution provided by the invention is：A method of storage spontaneous combustionof coal is prevented,
Coal is placed in closed space and oxygen-barrier, can also coal be subjected to premature oxidation processing so that coal lose from
The condition of combustion.
Further, the air where being placed in certain confined space and extracting coal out using wind turbine in confined space,
Make coal completely and air exclusion, loses the condition of spontaneous combustion.
Further, oxidation processes are carried out to coal by oxidant, to realize at the oxidation for storing coal in advance
Reason.
Further, the confined space is to be protected from light design.It prevents from causing heat between coal particles to increase due to illumination
And then cause spontaneous combustion.
Further, the oxidant is potassium hyperchlorate or sodium peroxide.Oxygen is released by oxidant decomposition so that
Oxygen carries out oxidation processes to coal, to reach the ability for making coal lose spontaneous combustion, extends autoignition time.
Further, the confined space is vacuum state.So that coal and oxygen isolation, lose the item of spontaneous combustionof coal
Part.
After using the above structure, the invention has the advantages that：（1）By wind turbine vacuumize process and utilize oxidant pair
In the oxidation processes of coal so that coal loses the condition of spontaneous combustion, prevents coal spontaneous combustion during storage, accident occurs；（2）
The property for generating oxygen is decomposed using strong oxidizer potassium hyperchlorate or sodium peroxide so that coal shifts to an earlier date oxygen during storage
Change, of low cost, operability is strong；（3）The storage space of coal prevents from causing coal to generate heat due to illumination using design is protected from light
It measures excessive, and then causes spontaneous combustionof coal.
Specific implementation mode
The present invention is described in further detail below.
Embodiment one：A method of storage spontaneous combustionof coal is prevented, coal is placed in closed space and oxygen-barrier,
Can also coal be subjected to premature oxidation processing so that coal loses the condition of spontaneous combustion.
Coal is placed in certain confined space and utilizes the air where wind turbine extraction coal in confined space so that
Coal completely and air exclusion, loses the condition of spontaneous combustion.By oxidant to coal carry out oxidation processes, with realize in advance for
Store the oxidation processes of coal.Confined space is to be protected from light design.
Oxidant is potassium hyperchlorate, and confined space is vacuum state, this is the preferred embodiment of the present invention.
Potassium hyperchlorate or sodium peroxide generate oxygen when decomposing, and oxygen carries out oxidation processes to storage coal, makes its mistake
The ability of spontaneous combustion is gone, and then prevents storage spontaneous combustionof coal；Coal is placed in the confined space being protected from light, and to the storage of coal
It deposits space and carries out vacuumize process, so that coal completely cuts off completely with air, prevent coal from spontaneous combustion occurs.
Embodiment two：A method of storage spontaneous combustionof coal is prevented, coal is placed in closed space and oxygen-barrier,
Can also coal be subjected to premature oxidation processing so that coal loses the condition of spontaneous combustion.
Coal is placed in certain confined space and utilizes the air where wind turbine extraction coal in confined space so that
Coal completely and air exclusion, loses the condition of spontaneous combustion.By oxidant to coal carry out oxidation processes, with realize in advance for
Store the oxidation processes of coal.Confined space is to be protected from light design.
Oxidant is sodium peroxide, and confined space is vacuum state, this is the preferred embodiment of the present invention.
Sodium peroxide has certain corrosivity, and is easy to deliquesce, and can be reacted with water, this is reduced to a certain extent
The problem of becoming damp of coal, and sodium peroxide can be reacted with nitric oxide and nitrogen dioxide, generate sodium nitrite and sodium nitrate, be risen
To certain nitrogen fixation, reducing coal, respiratory tract injures for caused by human body in transport or cargo handling process；Peroxidating
The oxygen that sodium and carbon dioxide reaction generate has certain oxidation for coal so that coal oxidation degree is deeper, drop
The probability of low spontaneous combustionof coal.
The present invention and its embodiments have been described above, this description is no restricted, it is illustrated above also only
It is one of embodiments of the present invention, actual structure is not limited to this.All in all if the ordinary skill people of this field
Member is enlightened by it, without departing from the spirit of the invention, is not inventively designed similar to the technical solution
Frame mode and embodiment, be within the scope of protection of the invention.
